Supradapedon revisited: geological explorations in the Triassic of southern Tanzania

The upper Triassic deposits of the Selous Basin in south Tanzania have not been prospected for fossil tetrapods since the middle of last century, when Gordon M. Stockley collected two rhynchosaur bone fragments from the so called "Tunduru beds". Here we present the results of a field trip conducted in July 2015 to the vicinities of Tunduru and Msamara, Ruvuma Region, Tanzania, in search for sim...

3d Geological Mapping: an Inescapable Evolution for National Geological Surveys

According to EuroGeoSurveys, the European Geological Surveys association, “Geological spatial data and models describe the solid Earth’s surface and subsurface on-shore and off-shore, its nature, structure, properties, dynamics and evolution over time; including its related (geo)resources and (geo) hazards”. This illustrates a modern vision of the core mission that National Geological Surveys h...

Mid and Far Infrared Surveys with ISO

We present the results of the extragalactic surveys performed at 15 and 175μm using the ISOCAM and ISOPHOT instruments on-board the Infrared Space Observatory (ISO). The number counts at both wavelengths present a strong evolution. The preliminary study of the individual galaxies responsible for this evolution suggest that more star formation was hidden by dust at redshifts around z = 1−2 and i...
